Strong magnetic proximity effect in Van der Waals heterostructures driven by direct hybridization
C. Cardoso, A. T. Costa, A. H. MacDonald +1
We propose a new class of magnetic proximity effects based on the spin dependent hybridization between the electronic states at the Fermi energy in a non-magnetic conductor and the…
Non-reciprocal magnons in a two dimensional crystal with off-plane magnetization
M. J. T. Costa, J. Fernández-Rossier, N. M. R. Peres +1
Non reciprocal spin waves have a chiral asymmetry so that their energy is different for two opposite wave vectors. They are found in atomically thin ferromagnetic overlayers with i…
Microscopic origin of subthermal magnons and the spin Seebeck effect
I. Diniz, A. T. Costa
Recent experimental evidence points to low-energy magnons as the primary contributors to the spin Seebeck effect. This spectral dependence is puzzling since it is not observed on o…
Dynamics of the Two-Site Hubbard Model
A. T. Costa, M. T. Thomaz
The dynamical evolution of a two-site Hubbard model is derived in the presence of an uniform external magnetic field for a general initial state. The time evolution of the half-fil…
